Subject: [PATCH] feat(ui): filter already-added chars from participant
 dropdown
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Character dropdown in add-participant picker excluded characters already
in the encounter. Prevents dup-add at the source — user can only select
chars not yet participating.
